Making some solid progress getting the core mechanics of a primitive 3D racing game wired up. Player movement has becoming much smoother since last night, and some animations help provide feedback. Next I'm going to try to wire up the lap/race mechanics followed by some primitive AI.

I'm afraid that performance may become a limiting factor soon. After building a map with just 100 billboards on it, I was already saw some strain on the framerate. I'm going to keep pushing forward regardless, but I could see this forcing me to cut some features early.
